Cycle and period

In short

  • Perimenopause is the transition years before menopause; one of the first signs is often a change in your period pattern.
  • Regularly noting period start and end dates, bleeding amount and gaps shows the change more clearly than memory.
  • Notes on hot flashes, night sweats, sleep and mood can be kept with a short, repeatable scale.
  • Records do not diagnose anything; your doctor evaluates what they mean.
  • If your bleeding gets heavier, or you bleed after 12 months without a period, see your doctor.

For a while now your periods have not been the same: sometimes they come early, sometimes they skip a month. You wake up sweating at night and feel a tiredness during the day you cannot explain. In their forties, many women start noticing changes like these. In this post we explain how to record cycle changes and the symptoms that come with them as menopause approaches, and how to bring those records to your doctor.

What is perimenopause, and why keep a record?

Menopause is when periods naturally come to an end. The few years before it are called perimenopause. During this time, the amount of hormones your ovaries produce starts to fluctuate, and these fluctuations can show up in different ways.

Perimenopause is different for everyone. Some people have hardly any symptoms; for others, symptoms have a noticeable effect on work, sleep and relationships. Because symptoms shift slowly over months, it is hard to answer "was it like this last month too?" from memory.

This is where keeping a record helps. Regular notes over a few weeks, or even a few months, show you and your doctor more clearly what happens and how often. Remember: records are not a diagnosis. Your doctor evaluates what a change means.

Which cycle changes should you note?

One of the first signs of perimenopause is often a change in your period pattern. Cycles may get shorter or longer, some months your period may not come at all, and bleeding may get lighter or heavier. That is why a cycle record rests on a few simple details:

  • Period start and end date: Write down the first and last day of each period.
  • Bleeding amount: Use the same scale every day, such as light, medium or heavy.
  • Bleeding between periods and spotting: Note any bleeding outside your period with its date.
  • Skipped months: If your period did not come, record that as information too.
  • Pain and other symptoms: Notes such as cramps, headaches or fatigue.

For a more general list of what you can include, see our post on what to note when tracking your period. What matters is writing the same details in the same way every month; that way, the differences between months become visible on their own.

You can also set yourself a goal for how long to keep the record. Even a few weeks of notes give a clearer picture than memory; if you keep going for a few months, trends such as cycles getting longer or shorter, or bleeding changing, become more visible. If you miss a month, there is no need to start over; just pick up where you left off.

Hot flashes, sleep and mood: short, repeatable notes

In perimenopause, changes can happen beyond your cycle too. Hot flashes, night sweats, trouble falling or staying asleep, mood swings, and problems with focus and memory are among the commonly mentioned symptoms. You do not have to write about all of them at length.

  1. Hot flashes: What time of day they happen, roughly how long they last and how intense they are (mild, moderate, intense).
  2. Night sweats and sleep: How many times you woke up at night and how rested you felt in the morning.
  3. Mood and energy: A one-word rating or a score from 1 to 5 at the end of the day.
  4. Possible triggers: Your own observations, such as a hot room, a stressful day, caffeine or alcohol.
  5. Medications and supplements you take: Write down the name and when you started; if you are thinking about a change, talk to your doctor or pharmacist.

Be kind to yourself while keeping your notes. What you are going through in this phase is not a failure or "overreacting"; it is part of a natural transition your body is going through. The point of keeping a record is not to control everything, but to understand better what you are experiencing and to have concrete information when you ask for support. Some days you may not want to write anything; that is normal too.

If you want to share with the people close to you at home or at work, your notes can be a starting point for that as well. A concrete sentence like "I have been waking up often at night for the past two weeks" makes it easier to explain what you are going through.

How do you bring your records to your doctor?

Because there is no routine test that confirms perimenopause on its own, doctors usually look at your age, symptoms and period history together. That is why well-kept notes make the appointment easier. Before your visit, put together a short summary of the last few months: cycle lengths, changes in bleeding amount, the two or three symptoms that bother you most, and your questions.

Some situations call for seeing a doctor without waiting. If your bleeding is heavier than before, if you bleed between periods, if you notice a symptom such as heart palpitations, or if you bleed after 12 months or more without a period, see your doctor. If you have very heavy bleeding along with dizziness or feeling faint, call the emergency number in your country.

We have gathered in detail what to share when your period pattern changes in our post on what to tell your doctor when your period changes. If changes in your mood last a long time or make daily life hard, be sure to talk about that too; asking for professional support can be a natural part of this phase.

After the appointment, add your doctor's recommendations and the date of your next check-up to your notes. That way it is easier to talk through what has changed at your next visit.

How do you record these changes in Oveluni?

When you choose the Women's profile in Oveluni, the Cycle section opens. You can record the days your period starts and ends with Record bleeding in the Quick add menu. You can mark your mood and energy with the Daily check-in and write down observations such as hot flashes or sleep with A note. The Insights screen shows your recorded period lengths and daily observations; if you like, you can bring a time range to your doctor as a PDF report. "Dates, just as you recorded them. Unrecorded days do not imply anything about your cycle." A fertility estimate is optional, off by default and can't be used to prevent pregnancy. Oveluni is coming soon to the App Store.
